Product classification
HS code for Boring-milling machine: 8459.39
Machine-tools, for boring-milling by removing metal, other than numerically controlled.
Classification of boring-milling machine under HS 8459.39
HS code 845939 is designated for machine-tools capable of performing both boring and milling operations by removing metal, specifically those that are not numerically controlled. This classification covers versatile machines that combine the precision of boring (enlarging or refining holes) with the surface-shaping capabilities of milling (removing material with a rotating cutter). The "not numerically controlled" aspect is a key differentiator, indicating that these machines operate through manual or mechanical controls rather than automated computer programming. These machines are widely used in workshops and manufacturing facilities where flexibility and precision in both hole-making and surface machining are required without the complexity of NC systems.

Codes often confused with 8459.39
Common mistake. Misclassification often occurs with numerically controlled versions or single-function machines. HS 845931 specifically covers numerically controlled boring-milling machines, which perform the same combined operations but with automated precision. HS 845949 is for boring machines that only perform boring operations, lacking milling capabilities. Similarly, HS 845959 covers milling machines that primarily perform milling, without significant boring functionality. HS 8457 is for machining centers, which are typically numerically controlled and can perform a wider array of operations, including boring and milling, often with automatic tool changers. Careful consideration of the machine's primary functions and control system is essential.
Top exporters and importers of HS 845939 (the code used for boring-milling machine), 2025
In 2025, the largest exporter of HS 845939 (the code used for boring-milling machine) in UN Comtrade data was China, with 41% of world exports; the largest importer in UN Comtrade data was India, with 20% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about boring-milling machine
What is the HS code for Boring-milling machine?
The HS code for Boring-milling machine is 845939 (Machine-tools; for boring-milling by removing metal, other than numerically controlled). The HS code for a boring-milling machine that is not numerically controlled is 845939.
How do I classify Boring-milling machine for customs?
Boring-milling machine is classified under HS code 845939 — Machine-tools; for boring-milling by removing metal, other than numerically controlled. This is a 6-digit subheading level code.
What is the primary distinction between HS 845939 and HS 845931?
The primary distinction lies in the control mechanism. HS 845939 covers boring-milling machines that are not numerically controlled, relying on manual or mechanical operation. In contrast, HS 845931 is specifically for numerically controlled boring-milling machines, which are automated via computer programming.
Which countries are the top exporters of boring-milling machine (HS 845939)?
In 2025, the top exporters of HS 845939 (the code used for boring-milling machine) in UN Comtrade data were China ($26M, 41% of world exports), Germany ($5.6M) and Denmark ($5.4M). World exports came to about $63M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of boring-milling machine (HS 845939)?
In 2025, the top importers of HS 845939 (the code used for boring-milling machine) in UN Comtrade data were India ($17M, 20% of world imports), Russia (about $13M) and Thailand ($8.1M). World imports came to about $88M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
